Flooded Farms, USA – Across the Midwest, torrential rains have soaked the fields, leaving the sodden soil unsuitable for planting millions of acres with corn, soybeans, and other crops, presaging a terrible harvest. Seeds are usually in the ground this time of year. But thanks to floods, unrelenting rains, hail, and scores of tornadoes—nearly 200 more than average by this point in the year—the season is off to one of the worst starts in history. Every day tractors don’t enter the fields means a higher chance of crop failure. On May 28, the USDA announced that US farmers have just 58% of their corn crop in the ground (versus a five-year average of 90% by this time) and 29% of the soybean crop (compared to 66%). Those are among the lowest rates in history. Other farmers may end up planting nothing and have declared a total crop loss.

Nuclear Testing Legacy

Cracks in a dome built over a crater left by a 1958 nuclear blast in the Marshall Islands may now be leaking radioactive contamination around Enewetak Atoll.

The Runit dome was built by the United States in 1977, designed to also contain radioactive debris from other nuclear tests in the Pacific between 1946 and 1958. But the new cracks and rising sea levels threaten to inundate the atomic dump, further contaminating the Pacific atoll.

Some of the Enewetak residents evacuated before the blast were finally allowed to return in 1980 after the dome was completed and the Marshall Islands government accepted the U.S. cleanup efforts as final.

Global Warming

Global warming and more storms

The type of stalled jet stream pattern that brought almost daily rounds of severe storms to North America and parts of the Mediterranean during the latter half of May is linked to the record warming of the Arctic.

Researchers from Germany’s Alfred Wegener Institute (AWI) combined two models that use machine learning to realistically reproduce the observed changes in the jet stream. They say it’s the first time artificial intelligence has been used in climate modeling.

“Our study shows that the changes in the jet stream are at least partly due to the loss of Arctic sea ice,” said Markus Rex of AWI. “If the ice cover continues to dwindle, we believe that both the frequency and intensity of the extreme weather events – in the middle latitudes will increase.”

Global Temperature Extremes

The week’s hottest temperature was 119 degrees Fahrenheit (48.3 degrees Celsius) in Jacobabad, Pakistan.

The week’s coldest temperature was minus 110.0 degrees Fahrenheit (minus 78.9 degrees Celsius) at Russia’s Vostok base, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Disease

Ebola – DR Congo

A decline in the number of confirmed Ebola virus disease (EVD) cases has been reported this week (22 to 28 May). Over the past seven days, a total of 73 new confirmed cases were reported compared to the previous where 127 new confirmed cases were reported. This should be interpreted with caution given the complex operating environment and fragility of the security situation.

African Swine Fever – North Korea

North Korean health authorities have reported an outbreak of African Swine Fever. The outbreak occurred at Buksang cooperative farm, Ri, Usi, Chagang-Do where 77 cases were reported on a farm of 99 pigs. The remaining 22 pigs were culled.

Bee Disease – Scotland

A case of European Foulbrood (EFB) was confirmed in West Lothian following laboratory diagnosis by Science and Advice for Scottish Agriculture (Sasa). It is a disease that spreads between hives, mainly by beekeepers, their tools and contaminated equipment.

Global Volcanic Activity – Ongoing Activity for the week of 22 May – 28 May 2019

Agung | Bali (Indonesia) : PVMBG reported that at 1923 on 24 May an explosion at Agung ejected incandescent material radially onto the flanks as far as 3 km from the crater rim, setting fire to some vegetation. A dense gray-white ash plume rose 2 km and, based on satellite data, drifted SW, causing thick ashfall in several villages to the S. Roaring was audible from the Agung Volcano Observatory in Rendang (about 8 km SW). According to a news article several flights to and from Australia were cancelled or diverted, though the International Gusti Ngurah Rai (IGNR) airport (60 km SW) in Denpasar was not closed. The Alert Level remained at 3 (on a scale of 1-4) with the exclusion zone set at a 4-km radius.

Aira | Kyushu (Japan) : JMA reported that during 22-23 May two explosions at Minamidake crater (at Aira Caldera’s Sakurajima volcano) produced plumes that rose 1.6 km above the crater rim and ejected material as far as 900 m. Crater incandescence was periodically visible. Very small eruptive events were recorded during 24-27 May. The Alert Level remained at 3 (on a 5-level scale).

Dukono | Halmahera (Indonesia) : Based on satellite and wind model data, and notices from PVMBG, the Darwin VAAC reported that during 22-28 May ash plumes from Dukono rose to altitudes of 2.1-3 km (7,000-10,000 ft) a.s.l. and drifted in multiple directions. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

Ebeko | Paramushir Island (Russia) : A thermal anomaly over Ebeko was identified in satellite images during 16-17 May. Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 16-20 May that sent ash plumes up to 2.5 km (8,200 ft) a.s.l. Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Etna | Sicily (Italy) : INGV reported that gas emissions of variable intensity were observed rising from Etna’s summit craters during 20-26 May; weather conditions often prevented views. Weak and diffuse ash emissions occasionally rose from the New Southeast Crater (NSEC). An ash plume rose from Bocca Nuova Crater on 23 May.

Ibu | Halmahera (Indonesia) : The Darwin VAAC reported that during 23-24 May ash plumes from Ibu rose to altitudes of 2.4-2.7 km (8,000-9,000 ft) a.s.l. and drifted SE based on satellite data. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to stay at least 2 km away from the active crater, and 3.5 km away on the N side.

Karymsky | Eastern Kamchatka (Russia) : KVERT reported that a thermal anomaly over Karymsky was visible in satellite images during 17-21 May. An ash plume drifted 9 km SW on 21 May. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Klyuchevskoy | Central Kamchatka (Russia) : KVERT reported that a weak thermal anomaly over Klyuchevskoy was identified in satellite images on 17, 19, and 21 May. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Krakatau | Indonesia : PVMBG reported that Anak Krakatau’s seismic network detected 26 eruptive events during 20-26 May. None of the events were followed by visible ash emissions, though observations were hindered by fog. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km radius hazard zone from the crater.

Merapi | Central Java (Indonesia) : PVMBG reported that on 11 May the lava dome at Merapi had an estimated volume of 458,000 cubic meters, based on analyses of drone footage, and remained unchanged at least through 26 May. The dome morphology remained relatively unchanged, as most of the extruded lava fell into the upper parts of the SE-flank Gendol River drainage. One block-and-ash flow traveled 1.1 km down the Gendol drainage. The Alert Level remained at 2 (on a scale of 1-4), and residents were warned to remain outside of the 3-km exclusion zone.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch’s lava dome was identified daily in satellite images during 17-24 May. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Soputan | Sulawesi (Indonesia) : PVMBG reported that during 22-28 May white plumes rose as high as 100 m above Soputan’s summit. On 27 May white-to-gray plumes rose 150 m high. The Alert Level remained at 3 (on a scale of 1-4). The public was advised not to approach the craters within a radius of 4 km, or 6.5 km on the WSW flank.
